Freight class 150
Class 150 is the band for freight with a density of 6 to 7 lb/ft³.
The density range
A shipment is class 150 when its density is 6 up to but not including 7 lb/ft³. Density is the total weight of the shipment divided by the total cubic feet it occupies, pallet and packaging included.
A shipment that lands in class 150
A standard 48 × 40 inch pallet, 48 inches tall, weighing 350 pounds.
48 × 40 × 48 = 92,160 cubic inches ÷ 1,728 = 53.33 cubic feet
350 ÷ 53.33 = 6.56 lb per cubic foot → class 150
Freight that usually lands here
Typical examples include automotive sheet metal parts, bookcases, assembled furniture parts.
Treat these as illustrations rather than a lookup. Density decides the band, so the same product can fall either side of a line depending on how it is packed, palletised and wrapped.
What to watch on class 150
Bulky but light. Freight in this band takes real trailer space relative to what it weighs, and the rate reflects that.
Where class 150 sits
The next band down is class 125, which covers denser and cheaper freight. The next band up is class 175, for lighter freight at a higher rate.
